Summary: Well-dispersed Pt quantum dots were successfully deposited onto a PDI supramolecular nanorods surface, forming Pt QDs/PDI composites with excellent photocatalytic properties in the degradation of phenol. The enhanced photocatalytic performance can be attributed to the efficient trapping and transporting of electrons by Pt QDs, which also act as active sites during the photocatalytic reaction, leading to high stability and utilization in water environmental purification.

Summary: Antibiotic contamination is a growing concern, leading to increased scrutiny on solutions like the AgAgCl/WO3/g-C3N4 (AWC) nanocomposites for trimethoprim degradation. Experimental results showed high efficiency with 99.9% of TMP degraded within 60 min using AWC at 0.5 g/L concentration. The proposed double photoelectron-transfer mechanism and identification of degradation pathways through theoretical calculations and experiments further support AWC as a promising photocatalyst for removing TMP from aquatic environments.

Summary: The novel plasmonic Ag/AgCl@LaFeO3 (ALFO) photocatalyst showed enhanced photocatalytic activity in controlling harmful algal blooms (HABs) under visible light. ALFO-20% demonstrated higher light absorption capacity and lower electron-hole recombined rate compared to pure LaFeO3 and Ag/AgCl. Furthermore, ALFO-20% efficiently removed chlorophyll a from HABs, altered algae cell membrane permeability and morphology, disrupted photosynthesis and antioxidant systems, reducing secondary pollution and preventing HAB recurrence.

Summary: Efficient visible light photocatalytic elimination of pharmaceutical factory wastewater was achieved by introducing hybrid Ag/AgCl nanoparticles into Ti3+ self-doped TiO2 mesocrystals. The Ag/AgCl@Ti3+-TiO2 mesocrystals showed superior performance in degrading tetracycline under visible light, mainly attributed to the continuous attacks of photo-generated holes and radicals on tetracycline molecules.

Summary: The rod-like Ag/AgCl/BiOCl materials were successfully fabricated by calcination of the self-sacrificial template of silver/bismuth bimetallic-organic frameworks in order to achieve more desirable photocatalytic activity towards tetracycline. The obtained Ag/AgCl/BiOCl catalyst exhibited enhanced light absorption ability in visible light region and superior photocatalytic activity compared to BiOCl, with remarkable stability during photocatalytic reactions. This work opens up new perspectives for advanced uniform-sized photocatalytic catalyst using bimetallic MOFs as self-sacrificial templates.

Summary: In2S3/BiOI composites synthesized at room temperature significantly enhance the photocatalytic degradation of tetracycline hydrochloride under visible light irradiation. The heterojunctions of the composites enhance the separation ability of photogenerated carriers, with the 7-In2S3/BiOI composite achieving the best performance. The photocatalytic mechanism of In2S3/BiOI composites involving superoxide radicals and holes is proposed based on photo-electrochemical characterization and free radical tests.

Summary: Recent developments in the field of nanomaterials have shown the importance of using doping techniques to achieve multifunctionality in materials. In this study, Sb-doped SnO2 nanoparticles were successfully prepared using a sol-gel approach. Various characterization techniques were used to investigate the effect of Sb doping on the structural and optical properties of SnO2, as well as the photocatalytic capabilities of the prepared nanoparticles. The results showed that Sb doping influenced the crystallite size and band gap energy of SnO2, leading to enhanced absorption in the visible light range and improved photocatalytic activity.

Summary: Bismuth ferrite (BiFeO3) is a potential material for removing industrial dyes from water through the photocatalysis process. Glass-ceramic with a composition of Bi2O3-Fe2O3-BaO-B2O3 was fabricated to utilize the BiFeO3 phase. The sample heat-treated at 480 degrees C for 2 hours showed the maximum degradation of Methylene Blue (MB) dye of -69% in 300 minutes. The stability of the fabricated samples was checked using XRD pattern and SEM micrographs, and MB dye degradation was calculated using RGB values obtained from a smartphone app.
